This compensator automatically adjusts carb jetting for all temperatures and is set to work with -20F (-29C) carb jetting for snowmobiles. It can easily be adjusted, however, to work with jetting for any temperature. There is an external screw which easily provides manual altitude adjustment effective for up to a 6000 foot (1800 meter) elevation change. We recommend this compensator for the user who wants "set and forget" temperature adjustment with normally less than 2000 feet of elevation change or occasional mountain riding. The standard model will work on almost any snowmobile except 4-strokes with CV carbs and it will not work on '01-'02 Ski-Doos with flatslide carbs. We have a model specific kit for Polaris with air box vented TM flatslide racked carbs, but the standard snowmobile Tempa Flow will also work on Polaris. We have a specific kit for both the Arctic Cat Firecat and Ski-Doo XP's with TM flatslide racked carbs.
